Answer: P=51

--

Steps for Solving Linear Equation: 20−9=5p+12

--

Subtract 9 from 20 to get 11.

`11=5p+12`

Swap sides so that all variable terms are on the left hand side.

`5p+12=11`

Subtract 12 from both sides.

`5p=11-12`

Subtract 12 from 11 to get −1.

`5p=1`

Divide both sides by 5.

`p=5-1`

Fraction 5−1​≈−0.2 can be rewritten as −51​=−0.2 by extracting the negative sign.

`p=-51`

Answer 2

-7

Explanation:

2p-9=5p+12

2p-9-12=5p

-21=5p-2p

-21=3p

p= -21/3

p= -7
